TIRE-VALVE-UNSEATING DEVICE.

Amerlca, and resident of Barton, county of Belmonhand State of Ohio, have invented .certain new and useful Improvements in Tire-Valve-Unseating Devices, of which the following is a specification.

This invention relates broadly-to valveunseating devices, and more particularly to a device for maintaining a tire-valve in unosition.

The primary object or the invention is to provide a device whereby the valve of a pneumatic tire may be depressed to and maintained in unseated position, as for releasing the air from the tire.

A further object is to provide a tool designed for ready application to a valve-tube and which involves a spring structure adapted for assuming clamping engagement with said valve-tube in a position in which a valve-depressing member is held in valveunseating position.

A still further object is to provide a device of the character mentioned which may be applied instantly by slipping the clamp longitudinally the valve-tube and in which the valve-depressing member is so located that it is guided or directed into valveunseating engagement with the outwardly extending end of the valve-stem by the mere act of applying said clamp, or without the exercise of care or attention on the part of the user.

With these and other objects in View, the invention resides in the features of construction which will hereinafterbe exemplified, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of the in vention;

Fig. 2 is an enlarged side elevation of the same, illustrating its application; and

Fig. 3 is a similar elevation viewed from a point at a rightangle to the view point in Fig. 2.

In said drawings like designating characters distinguish like parts throughout theseveral views.

The invention 1s composed of a slngle length of WIIG, one end-portion of whlch 1s Specification of Letters Patent.

bent to form two substantially parallel l members 1 and 2 which are joined at one end by a spring coil 3, said member 1 con sisting of along terminal finger adapted to yieldinglyen age a side of the body-portion A and constituting a part of a valve-tn of a clamp whereby such tube may be adjustably embraced. The portion of said clamp opposed to and cooperating with said finger l is constituted by a loop of approximately rectangular form and consisting of two horizontally disposed substantially semi-circular members 5 and 6, the lower of which is adapted to conformably embrace the body-portion 4 of said valve-tube while the upper member 6 thereof is adapted to conformably embrace the usual reduced endportion 7 of said tube. Further, said upper member 6 of said loop is so located that it will seat upon the shoulder 8 intermediate the portions 4: and 7 of said tube for preventing advancement of the clamp over the tube beyond the point at which the valve is adequately unseated, as will subsequently be explained;

Said rectangulartube-embracing loop of the clamp has its free end composed of a substantially vertical member 9 intermediate and uniting the corresponding ends of the semi-circular members 5 and 6, while its opposite end is composed of the lower portion of a vertical member 10 which rises from the corresponding end of the member 5 and which is closely embraced at a point approximately midway between its ends by a coil 11 formed in the wire at the corre sponding end of the member 6 of said loop.

it will enter the end of the Valve-tube A in accurate axial alinement with the latter when the clamp constituted by the rectangular loop and spring finger 1 is slipped over saidtube. nal member 12 accurately engages the out- Thus, when applied, the termimally dis osed in a central or axial position within said tube. To insure a ainst said member 12 missing the end of sai stem when introduced, as when the latter occupies a slightly inclined position, as sometimes happens due to the valve occupying an improperly or imperfectly seating position, the inner end of said member is prefe'rably flattened or upset slightly to form a head 15 approximating in shape that com monly employed on small nails or brads. The length of said member 12 is preferably so proportioned relatively, or' has its end so located with respect to the position of the loop member 6, that, when the clamp occup'ies seated position with said member 6 resting upon the shoulder 8 of the valvetube, it will have depressed the valve stem 14 to an extent which efiectually unseats the valve.

As is apparent, application of the device to valve-unseating position upon the valvetube is the work of an instant. Further, while the clamp is self-retaining the spring finger 1 forming a part thereof is sufliclently resilient to permit of application and removal without injury to the threads of the valve-tube.

What is claimed is- 1. A tire-valve-unseating device consisting of a single-wire bent to form a resilient clamp embodying a spring coil, said clamp being adapted for slipping over a valve-tube and having a member designed to engage and seat upon the valve-stem for depressing the latter,

2. A tire-valve-unseating device composed of a single length of wire shaped to form opposed resilient members adapted for assuming clamping engagement with a valvetube, a spring coil intermediate said mem-' .bers, and a member adapted for entrance within the end of said tube for engaging and depressing the valve-stem.

3. A tirevalve-unseating device composed wholly of a single length of wire and embodying opposed resilient members adapted. to be slipped longitudinally over the end of a valve-tube and to assume clamping engagement with the latter, and a member formed of one of the wire terminals carried 'in fixed relation to said members and adaptthe valve-stem.

4. A tire-valve-unseating device composed wholly of a single length of wire and adapted to seat upon a valve-tube in clamping relation to the body portion of the latter, said device comprising a pair of clamp-members designed to be slipped longitudinally into gripping engagement with said tube, one of said members embodying means for applied to said tube.

limiting the extent to which the members may be applied, and a member adapted to automatically assume valve-unseating relation to the valve-stem as said members are 5. A tire-valve-unseating device adapted to seat upon a valve-tube in clamping relation to the latter, said device being composed wholly of a single length. of wire bent to form opposing clamp-members of which one embodies a stop adapted-to seat against the shoulder locatedintermediate the body of the valve-tube and the reduced end of the latter, and a terminal member adapted to automatically seat upon and depress the valve-stem as the clamp-members are moved to seated position.

' 6. A tire-valve-unseating device adapted to seat upon a valve-tube in clamping relation to the latter, said device comprising a single length of wire bent to form oppos- 1ng clamp-members, a spring coil formed intermediate said members, and a terminal member so located with respect to said clamp-members that the act' of applying the latterserves to carry said terminal member into valve-unseating relation to the valvestem.

7. A tire-valve-unseating device adapted to seat upon a valve-tube in clamping relation to the latter, said device comprising a single length of wire bent to form opposmg clamp -members and an intermedlate sprlng coil, the opposite wire terminal being shaped to constitute a member which M0 automatically depresses the valve-stem as said clamp-members are applied in seating position.

8. A tire-valve-unseating device adapted .to seat upon a valve-tube in clamping rela- .engaging member disposed in opposed relation to said finger.

9. A tire-valve-unseating device adapted to seat upon a valve-tube in ,clamping relation to the latter, said device comprising a single length of wire shaped to form a finger at one of its terminals and a valvestem-engaging member at its opposite terminal, and an intermediate portion adapted to partially embrace the valve-tube and disposed in'opposing relation to said finger.
